Membrane separation type solvent dehydration system

Great attention is recently being paid to global environmental issues, and it is now conceivable that companies will need to treat used solvents themselves. In consideration of this kind of social issue, we have developed a “membrane separation type solvent dehydration system,” which uses a polyimide membrane with superior dehydration properties developed by Ube Industries, Ltd. in combination with our own distillation and concentration technology that has resulted in solvents being more easily recovered.

THREE:The man, still running, dodged from the road and started across country. Cairness wheeled and followed him. It was open ground, with not so much as a scrub oak or a rock in sight. The thick darkness offered the only chance of escape. But Cairness had chased yearlings in nights as black, and had brought them back to the herd. Down by the creek where the trees were thick, there would have been a good chance for escape, almost a certainty indeed, but there was little here. The man dodged again. It was just to that very thing that the pony had been trained. Habit got the better of stampede with it. It, too, dodged sharply.
  • 1Under the distillation system, even in case of azeotropic solvent compositions, this system which remove water vapor by the polyimide membrane will easily dehydrate.
  • 2In comparison with the distillation system, it significantly saves on use of steam.
  • 3Dehydration can be performed through merely supplying evaporated vapor to the membrane module and maintaining the differential pressure between the permeable side and the impermeable side.
  • 4Solvent purity of 99.9% or more can be achieved by carrying out dehydration with a polyimide membrane only.
  • 5The polyimide membrane has superior heat and solvent resistance. Therefore, the vapor permeation system reduces contamination of the membrane and thus extends its life.
THREE:Landor interrupted by taking the slipper from Felipa's foot and killing with it a centipede that crawled up the wall of the abode. "That's the second," he said, as he put the shoe on again. "I killed one yesterday; the third will come to-morrow." Then he went back to his chair and to the discussion, and before long he was called to the adjutant's office.

The aromatic polyimide membrane is highly permeable to water vapor but less permeable to vapors of organic compounds such as alcohol etc.

THREE:"Take care!" yelled Cairness, as Felipa, dazed and without breath, headed straight for the stream. He bent and snatched at her bridle, and, swerving, started up the sheer side of the hill. She clung to the mane instinctively, but her horse stumbled, struggled, slipped, and scrambled. She had lost all control of it, and the earth and stones gave way beneath its hoofs just as a great wall of water bore down the bed of the river, sweeping trees and rocks away, and making the ground quiver.Landor took his arm from the saddle and stood upright, determinedly. "We are going to stop this mob business, that's what we are going to do," he said, and he went forward and joined in a discussion that was[Pg 117] upon the verge of six-shooters. He set forth in measured tones, and words that reverberated with the restrained indignation behind them, that he had come upon the assurance that he was to strike Indians, that his men had but two days' rations in their saddle bags, and that he was acting upon his own responsibility, practically in disobedience of orders. If the Indians were to be hit, it must be done in a hurry, and he must get back to the settlements. He held up his hands to check a flood of protests and explanations. "There has got to be a head to this," his drill-trained voice rang out, "and I propose to be that head. My orders have got to be obeyed."
  • 1 Recovery of the detergent solvent Recovery of the cleaning solvent such as electronic parts industry, precision instrument industry.
  • 2Solvent recovery and the refinement Solvent recovery and the refinement such as chemical industry, an industry of medical supplies, food industry, the fermentation industry.
THREE:Then stand to your glasses steady,What had he done with four and thirty years, putting it at the very highest valuation? He had sunk so far below the standard of his youth that he would not be fit for his old companions, even if he had wanted to go back to them, which, except in certain fits of depression, he did not. His own mother cared very little what became of him. At Christmas time she always sent him a letter, which reached him much later, as a rule, and he answered it. His brothers had forgotten him. His sister, of whom he had been very fond once, and for whom he had hoped a great deal, had married well enough and gone to London; but she, too, had forgotten him long since.
